Method and user equipment for determining whether base station is genuine or rouge in wireless network

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments herein provide a method for determining whether a base station is genuine or rouge in a wireless network. If a received authentication key matches with the authentication key generated in the UE, the method includes identifying a base station as genuine base station and carrying out a normal procedure. If the received authentication key does not match with the generated authentication key, the method includes identifying the base station as a rouge base station. The authentication key can be a digital signature (DS), a Message Authentication Code-Integrity (MAC-I), and a hash of MIB/SIBs including PCI.
